Pajamas are to wear at home before you get dressed in the morning and when you're getting ready to go to bed. They're not day clothes, and they're certainly not work clothes.Same as bathing suits are to swim in, not go shopping or out to eat in.There should still be standards of what is appropriate attire for certain settings and what isn't. No sweatpants at weddings, no snow boots for ballroom dancing, no bathing suits in restaurants, no pajamas in the store or school.
